MCU temperature range copes with IoT environments
Summary
Bluetooth 5.2 LE radio supports Mesh, angle-of-arrival (AoA), and angle-of-departure (AoD) for direction finding, long-range (coded), and high-throughput modes. A RISC-V core optionally handles timing-critical controller tasks, freeing the programmer from Bluetooth LE interrupt latency concerns. A cryptographic toolbox (CTB) provides advanced security features, including an MAA for fast elliptic curve digital signature algorithm (ECDSA), advanced encryption standard (AES) engine, TRNG, SHA-256 hash, and secure boot loader. Internal code and SRAM space can be expanded off-chip through two quad-SPI execute-in-place (SPIXF and SPIXR) interfaces up to 512 MB each. It features an Arm Cortex-M4F CPU for efficient computation of complex functions and algorithms, and Bluetooth 5 LE radio designed for wearable and hearable fitness devices, portable and wearable wireless medical devices, industrial sensors/networks, Internet of Things (IoT), and asset tracking.
